我社的土壤粘重,过去采用点种浅播,常年亩产老是徘徊在200斤左右。花生生长期较短,如山东伏花生全生育期约130天。出土后在主茎上呈十字形生两对侧枝和若干不规则的二次侧枝。3—4片真叶时,花芽就开始分化,从分化到开花一般需要经过20—25天。受精后花瓣和花萼管很快枯萎脱落,3—4天后子房柄开始伸长,子房顶端变得又坚又硬,形状如针(叫果针)。子房怕光,它只有在土、水、气条件具备的情况下,才能发育成饱满的荚果。果针的入土能力与开花的早迟关系很大,以第一、二对侧枝上接近地面的 My society’s soil sticky, in the past using the point of planting shallow, perennial perennial hovering around 200 pounds. Peanut growth period is shorter, such as Shandong peanut whole growth period of about 130 days. After unearthed in the main stem was cruciform two pairs of collateral and a number of irregular secondary collateral. 3-4 true leaf leaves, flower buds began to differentiate, from differentiation to flowering generally takes 20-25 days. After fertilization, the petals and calyx tube soon wilt off, 3-4 days after the onset of elongation of the ovary, the top of the ovary becomes firm and hard, the shape of the needle (called the needle). Ovary afraid of light, it is only in the soil, water, gas conditions available to develop into a full pod. Fruit into the soil ability and flowering sooner or later have a great relationship to the first and second on the side of the ground close to the ground
